BASEBALL-GURVER.

Specification of Letters Patent.

Patented Mar. 2, 1920.

Application filed June 11, 1919. Serial No. 303,342.

To all whom it may concern.-

Be it known that I, HERBERT B. RioxnrsoN, a citizen of the UnitedStates, residing at Providence, in the county of Providence and State ofRhode Island, have invented certain new and useful Improvements inBaseball-Curvers, of which the following is a specification, referencebeing had to the accompanying drawings.

This invention relates to certain improve ments in base ball curvers andit is an object of the invention to provide a novel and improved deviceof this general character which may be readily applied to a digit of ahand and which serves to impart the desired spin or rotation to a ballwhen thrown to cause said ball to travel in a curve.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved baseball curver whereby certain important advantages are attained and thedevice rendered simple, nonexpensive and otherwise more convenient andadvantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitelyclaimed.

In order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accompanying drawingswherein- Figure 1 is a view in perspective of a base ball curverconstructed in accordance with an embodiment of my invention and inapplied position, the coacting hand being indi cated by dotted lines;and v Fig. 2 is an enlarged view partly in section and partly inelevation of the device as herein disclosed.

As disclosed in the accompanying drawings B denotes a band, preferablyelastic, adapted to be applied to a digit of a hand and disposedtransversely of said band B and secured thereto is an elongated metallicplate P. At its longitudinal center the plate P is provided with theoutstandingbeacl or corrugation 1, substantially semi-circular in crosssection. The bead or corrugation 1 affords a hump for contact with theperiphery of the ball and serves to materially increase the spin orrotation of said ball so that the same may be thrown to travel in acurve.

In practice the band B is applied to either the first or second fingerof the hand of the throwing arm, and between the first and sec ondjoints of such finger with the corrugation or bead in contact with theball. The desired curving of the ball in its travel is materiallyfacilitated by the increased rotation imparted to the ball by myimproved device as the ball leaves the hand.

The head or corrugation 1 is substantially rigid and extends in adirection circumferentially of the band B and the functioning of thedevice is materially enhanced by the cross sectional configuration ofthe bead or corrugation 1.

The opposite end portions of the plate P are returned to afford theinwardly directed extensions 2 overlying the inner face or surface ofthe band B and said band B is clamped between the extensions 2 and theplate P proper whereby said plate P is effectually maintained in appliedposition.

From the foregoing description, it is thought to be obvious that a baseball curver constructed in accordance with my invention is particularlywell adapted for use by reason of the convenience and facility withwhich it may be applied and assembled, and it will also be obvious thatmy invention is susceptible of some change and modification withoutdeparting from the principles and spirit thereof, and for this reason Ido not wish to be understood as limiting myself to the precisearrangement and formation of the several parts herein shown in carryingout my invention in practice except as here inafter claimed.

I claim:

1. A base ball curver comprising an elongated plate having anoutstanding bead ex* tending transversely thereacross, said bead beingsubstantially semi-circular in cross section, and means for attachingthe plate to a digit of a hand with the longitudinal axis of the plateextending longitudinally of the digit.

2. A base ball curver comprising a band adapted to surround a digit of ahand, a plate extending transversely of the band and secured thereto,said plate having a transversely extending corrugation roviding anoutstanding bead disposed circumferentially of the band.

In testimony whereof I hereunto aflix my signature in the presence oftwo witnesses.

HERBERT BRADFORD RICKETSON.

CHARLES W. GRAFTON, JAMES REILLY.
